因为branch and price算法就是branch and bound和column generation的结合体。 2 应用背景 branch and price算法就是branch and bound和column generation的结合体。具体是怎么结合的呢?先看一张BP的算法流程图,相信大家会清晰很多: 3 具体流程 我们知道branch and bound求解整数规划的过程,如果不知道看看下面这张图回...

In particular, we present a Branch&Price algorithm for the PLOHP and we develop a number of preprocessing techniques and decomposition strategies to dramatically reduce the size of its instances. Computational experiments show that the proposed approach is 10–30 $$imes $$ × faster than previous...

二、branch and price branch and price其实是column generation和branch and bound的结合。为什么要结合呢?前面的文章中介绍过,column generation是求解大规模线性规划问题的,注意是线性规划问题,不是整数或者混合整数规划问题。 因此在用column generation求解VRPTW的Set-Partitioning Model的时候,需要先将决策变量由整数松...
